In a statement to All Things Digital's Ina Fried, Microsoft Corp. (MSFT) acknowledged that it was aware of reboot issues afflicting earlier adopters of Windows Phone 8, and promised a swift fix would be delivered early next month over the air (OTA).

Comments a Microsoft source, "We’re continuing to investigate some reports of phones rebooting and have identified a cause with our partners. We are working to get an over-the-air update out in December."

While the comment contains no word on the scope of the issue, reportedly customers using Nokia Oyj.'s (HEX:NOK1V) colorful Lumia 920 and HTC Corp.'s (TPE:2498) 8X have been experiencing the annoying problem.

A handful of other bugs have also been reported. While some customers have been able to sync their devices with Bluetooth receivers, such as in-car infotainment systems, other users report that their devices refuse to sync or experience connectivity issues. Lumia 920 users also report experiencing poor battery life, but that problem may be on the OEM side, as Nokia has long struggled with battery life with its Lumia phones.
